Romney's Long March.

The article looks at the race for the 2012 U.S. Republican presidential nomination, focusing on candidate Mitt Romney. Topics discussed include his narrow victory in the Michigan and Arizona primaries, the surprisingly tenacity of his less-well-funded, strongly socially conservative opponent Rick Santorum, and how many Republican voters, particularly social conservatives and members of the Tea Party political organization, are put off by Romney's moderate conservatism. The article calls attention to the gaffes Romney has made by referring to his personal wealth.
